Compositional study of Ti-Nb oxide (TiNb₂O₇, Ti₂Nb₁₀O₂₉, Ti₂Nb₁₄O₃₉, and TiNb₂₄O₆₂) anodes for high power Li ion batteries.

ABSTRACT: Titanium niobium oxides (TNOs) are attractive anode materials for high power density Li-ion batteries. However, the details of capacity storage in TNOs are not fully understood today as it depends on the Ti and Nb composition and their changes in the oxidation state. This is further complicated by a wide variation in gravimetric capacities reported in the literature for TNO anodes. Therefore, in this work, we systematically synthesise TiNb₂O₇, Ti₂Nb₁₀O₂₉, Ti₂Nb₁₄O₃₉, and TiNb₂₄O₆₂ particles using the same solid state reaction approach and report their electrochemical properties via galvanostatic cycling, cyclic voltammetry, and the galvanostatic intermittent titration techni
